Use Zoho Sign to get Sales Order Signed

Use Zoho Sign to get Sales Order Signed

I see that Zoho Books has a digital signature option for the invoices now but we need it for the Sales Order. Any ideas how to access the Sales Order PDF in Zoho Finance to be accessible when creating a Zoho Sign document?

In the deal, Zoho Sign can access the Attachments related list in Zoho CRM, why can't it access the Zoho Finance related list? That would be one way to solve our issue, any ideas?

or

Is there a way to forward/transfer, something, the SO_PDF from the Zoho Finance related list to the attachments related list or to a Workdrive folder or somewhere that Zoho Sign can access?

Ideas, suggestions, and solutions appreciated.
